U.S. Supreme Court Chief Justice John Roberts arrives prior to President Barack Obama's State of the Union speech on Capitol Hill in Washington, in this file photo taken January 28, 2014. Roberts, who cast the decisive vote in 2012 to save Obamacare from a conservative legal challenge, could do the same this year in a major case questioning key health insurance subsidies.
